Alice Maguire and her three daughters are trying to get to the airport to pick up her husband/their father. But on the way there a tornado warning sounds and the trip gets too dangerous, so they stop on the highway and run to a house to take shelter. Nobody answers the door, so they all break into the cellar to wait out the storm. But then they discover that somebody is actually in the house above them, and then they get trapped in the cellar. There is much more to worry about than the impending storm, and their lives become endangered by something abnormal.
